Measurement locator and light shield for use in interactance testing of body composition and method for use thereof
First Claim
1. A light barrier and probe location device for use with a near infrared radiation interactance probe for measuring body composition on the upper arm of an individual, the device comprising:
- (a) a piece of drapable, flexible opaque material having an opening therein for receipt of the probe at a predetermined position, the material being sufficiently large to overwrap the arm of an individual to be tested,(b) adjustable fastening means on the piece of opaque material for removably attaching the piece of opaque material around the upper arm of an individual and allowing it to be held in place to exclude light to a probe inserted into the opening during the test and to be separated for removal from the arm after the test, and(c) a probe location member attached to the piece of opaque material in a position to determine the precise location of the probe opening when the opaque drape engages the individual'"'"'s upturned arm, the probe location member locating on the inside of the elbow of the individual.

Abstract
A light barrier and probe location device are disclosed for use with a near infrared interactance probe for measuring body composition on the upper arm of an individual while allowing the individual to conduct his/her own test at the same position on the arm each time and excluding ambient light. The device includes a piece of opaque material having an opening for the light probe, a probe location member removably attached to the material to position the light probe location opening and fastening means for attaching the opaque material around the arm of an individual after the probe location member locates the appropriate opening position to allow the individual to conduct his/her own test on him/herself.

6. A method of quantitative in vivo measurement of the type used for estimating body composition of an individual, the method using a near infrared interactance probe positioned on the biceps of the individual to be measured (tested person), the improved method allowing self-measurement at precisely the same position the biceps and excluding external light, the improved method comprising:
-
(a) measuring from the inside of the elbow on the arm of the tested person to determine the probe position, (b) setting such measurement on a flexible light shield drape attachment, (c) positioning the flexible opaque light shield drape having an access opening for the probe therein on the upper arm of the tested person so that such opening is at a predetermined point within the light shield drape and at a measured distance from the elbow and biceps of the tested person, (d) enclosing the biceps portion of the tested person'"'"'s arm with the opaque light shield drape, the drape holding itself in position, and (e) inserting the near infrared interactance probe in the opening in the flexible opaque light shield drape while it is in position by the tested person while the drape is closed in order to measure the body composition of the individual. - View Dependent Claims (7)
